Function decodeLocality

fdbclient/ManagementAPI.actor.cpp:1738–1748

Decodes the locality string to a pair of locality prefix and its value. The prefix could be dcid, processid, machineid, processid.

// Returns the list of IPAddresses of the workers that match the given locality.
// Example: locality="dcid:primary" returns all the ip addresses of the workers in the primary dc.
